Low temperatures can easily trigger acute heart attacks and strokes. Statistically, there is a “Double Peak” phenomenon during the day: the first peak occurs between 5:00 AM and 9:00 AM (from before waking up to 4 hours after), and the second occurs between 8:00 PM and 9:00 PM (after dinner).
As a cold snap approaches, we urge seniors and high-risk groups to take extra precautions. This is especially critical for those with diabetes, hypertension, high cholesterol, kidney disease, obesity, or habits of smoking and heavy drinking, as well as those with a family history of stroke or ischemic heart disease.
Here are 8 Essential Keys for Low-Temperature Health to help you and your family safely navigate the impact of a cold wave:
🌡️ The 8 Keys for Low-Temperature Health
- Stay Warm: Ensure bedrooms, bathrooms, and living rooms have adequate cold-proofing. When going out, use comprehensive protection, focusing on the head, neck, and extremities. Utilize scarves, hats, masks, gloves, socks, and non-slip shoes. Layer your clothing (the “onion” method) for easy removal.
- Warm Up Gradually: Do not rush into activity immediately after waking up. Drink warm water first and increase physical activity in a gentle, progressive manner.
- Avoid Overeating and Emotional Extremes: Drink warm water regularly to prevent blood from becoming too viscous. Eat high-fiber foods like vegetables and fruits to prevent constipation. Limit alcohol consumption and avoid sudden exertion, tension, excitement, or abrupt, strenuous exercise.
- No Bathing Immediately After Meals or Alcohol: If diagnosed as high-risk by a doctor, avoid solo mountain climbing or exercising in secluded areas. Do not soak in hot springs alone. Ensure the water temperature does not exceed 40°C and wait at least 2 hours after eating.
- Reduce Physical Stress: High-risk individuals should exercise regularly but must avoid high-risk time slots (early mornings or late nights). Avoid outdoor exercise during the winter dawn and wait at least one hour after dinner for digestion before moving.
- Maintain Chronic Condition Management: Take medications regularly and follow up with doctor appointments. Keep a log of your blood sugar, blood pressure, and lipid levels. Quit smoking, control your weight, and maintain a balanced diet.
- Carry Medical Info and Emergency Meds: Always carry a medical ID card noting your usual hospital, diagnosis, and drug allergies. If your doctor has prescribed emergency medication (like nitroglycerin), keep it with you at all times.
- Recognize Stroke or Myocardial Infarction: Remember these two life-saving rules:
- Time is Life, Do Not Hesitate: If symptoms like chest tightness, shortness of breath, or cold sweats occur (heart attack), or facial asymmetry, weakness on one side of the body, or slurred speech occur (stroke), seek medical help immediately.
- Call 119 for Correct Transport: If an acute attack is suspected, call 119. Professional paramedics can provide immediate first-aid during transport and ensure you reach the hospital fastest, which is critical for minimizing permanent damage.
